SHGNALATTACHMENTFOR HEADLIGHTS.

FSPEGIFIGATION forming part of Letters Fatent No. 680,773, dated August .20, 1901. Application filed May 10,1901. Serial No. 59,620- (No model.)

To all whom it may concern.-

Be it known that I, AMos BENJAMIN HAL- LER, a citizen of the United States, residing at Brunswick, in the county of Frederick and State of Maryland, have invented new and useful Improvements in Signal Attachments for Headlights, of which the following is a specification.

My invention has relation to classificationlights; and it consists inthe novel construetion and arrangement of its parts, as hereinafter described.

The object of the invention is to provide a device adapted to transmit light from one source to one or more receptacles or signalboxes known as markers and at the markers to illuminatesignals of different colors.

The device is especially designed to be used on a locomotive-engine and as a rearend signal for trains; but it may also be used to transmit light from a single source to distaut points for many purposes, such as illuminating signs and transparencies and for reading and illuminating in general, the advantage of the light so transmitted being that it is devoid of heat.

When used on locomotives and trains, the device is intended to take the place of the ordinary signal lamps now generally used. These lamps use coal oil and frequently smoke and go out. Also the glass becomes dampened with oil, which collects the dust and smoke, preventing the bright display of light, which sometimes misleads and causes accidents.

When applied to a locomotive, the device can be operated by the engineer from the cab, who can manipulate the parts so as to display signals of various colors or cut the light off altogether. There being no oil-light in the markers, there is nothing to collect foreign matter andno smoke to affect the sig-' nals. Consequently the device is reliable.

In the accompanying drawings, Figure 1 is a front elevation of an engine, showing the signal-light applied thereto. Fig. 2 is a side elevation of Fig. 1, partly in section. Fig. 3 is a top plan view of the markers and connections. Fig. 4 is a perspective view of the end of the reflector-shaft and its bearings. Fig. 5 is a vertical sectional view of the marker. Fig. 6 is a horizontal sectional view of the marker. Fig. 7 is an elevation of the upper tube ends, showing the reflector attached thereto. Fig. 8 is a side elevation of Fig. 7, and Fig. 9 is a detail View showing the means for attaching the tube-sections together.

. The signal, as shown in the accompanying drawings, is especially adapted to be used in connection with the headlight of a locomotive. The small reflector 1 is attached to the reflector-shaft 2, said shaft being journaled in the uprights 3 3. The reflector 1 is located within-the casing of the headlight 4-, the reflector 1 when in use being in such a position as not to interfere with the light from the lamp. One end of the shaft 2 passes laterally through the side of the headlight-casing and is provided with an opening adapted. to receive a pin 5, said pin also passing through a recess in the bearing 6, thus preventing the shaft 2 from rotating or Wabbling.

The uprights 3 3are attached at their lower ends to the chute 7, and said chute in turn is connected with the upper ends of the tubes 8 8. A marker 9 is located at each side of the boiler-front, the lower ends of the tubes 8 8 connecting with said markers in a mannor as shown in Fig. 1. Each marker 9 is provided with two light-openings 10 '10, and in the top of each marker is journaled a shaft 11. The glass annulus 12 is fixed to the top of the marker, and the glass annulus 13 is fixed to the shaft 11. These annuli come together and form a bearing and support for the shaft 11. The hood 11 covers and protects the said bearings. To the lower end of the shaft 11 the frame 15 is attached, the said frame being located in the interior of the marker 9. The top of the frame is provided with a light-cut-off 16, (see Fig. 6,) said lightcut-oif 16 being adapted at intervals to pass under the light-inlet opening 17 and cut off the light to the marker. The frame 15 is also provided with grooves 18 18, adapted to receive the colored glass 19. The glass 19 is at intervals adapted to be thrown behind the light-opening 10 10, and thus the color of the light from the marker is changed.

The top of each marker is provided with doors 20, through which the glass 19 may be removed from the frame 15 and new ones put in in case of breakage. Ihe upper end of theshaft 11 is provided with a lever 21. (See Fig. 3.) The upper end of the lever of the opposite marker is provided with a bellcrank lever 22. The rod 23 connects the end of the lever 21 with one end of the bell-crank lever 22. The rod 24 connects the other end of the bell-crank lever 22 with the cab of the engine.

In operation the rays of light from the headlamp 4 are thrown by the reflector-1 down into the chute 7 through the tubes 8 8 into the markers 9 9. Theinner surface of the chute 7, the tubes 8 S, and the markers 9 9 are highly polished. By manipulating the rod 24 and its connections the engineer can show either a green or white light in the markers or he can cut the light 01f altogether.

In case the headlight 4 should go out or for any other reason be rendered incapable the engineer can light the oil-lamps 25 25 in the markers and display the different colors by manipulating the rod 24:, as, above described.

As a means for holding the ends of the tubes 8 Sin place the lower ends of the bifurcations of the chute 7 are provided with springstrips 26, having at their lower ends'openings 27, said openings being adapted to receive projecting pins on the upper ends of the tubes 8 8. The rings 28 are then slipped down over the strips 26, and the jostling of engine will have a tendency to cause the said rings 28 to descend and make the strips 26 more firmly hold the pins at the upper ends of the tubes 8 8. The same kind of connection is made at the lower ends of the tubes 8 8, as indicated in Fig. 1, where they enter the light-inlet 17 of the markers. By providing a glass bearing between the shaft 11 and the top of the marker 9 the said bearing will not have to be oiled, and is of a durable nature, simple in its construction, and reduces the friction and wear to a minimum.

In applying the apparatus to the rear-end lights of a train the last light in the last coach is used, and from this light the rays are sent to the markers at the rear end of the coach,

thus making one light do the work of three,

which avoids the necessity of using oil in the markers and doing away with the disadvantages of the accumulation of dirt and smoke caused by the use of oil, as above described.

In order to spread the light more generally, the lamp 25, located in the marker 9, is provided with a highly-polished flange 29. The light falling on the flange is reflected through the light-openings l0 and the glass interposed behind the same.

Having described my invention, what I claim as new, and desire to secure byLetters Patent, is
